Assertions and Facts

LEDs do not heat up
This statement is true in the past, for LEDs with low power. As today‘s LEDs achieve high performance
on a few square millimeters, they are hot and must be cooled mandatory. The components used for cooling can be very warm.

LEDs are perfectly suited for all areas
LEDs are ideal for most applications. However, some environments are totally unsuitable, for example, very high ambiente temperatures.

LEDs with the same color temperature always have the same look.
Unfortunately, this statement applies to no Light source, with the exception of incandescent bulbs. Especially white LEDs are subject to production variations. After the production of LEDs, same light colors are sorted in the selection process (Binning). Different sorts  (Binnings)with the same color temperature can be lead to different appearance.
